Improve the usability
E.g., never use dialogs that have to be closed with the mouse. Especially the one that says that someone else has gone. Fine, but let me ignore it and continue my action. In fact, having to move my mouse around so much in general is bothersome. Keyboard shortcuts or other improvements would be welcome.
Reducing the amount of clicking and mouse-movement is one of our goals for the UI revisions that are in the works.

A good example: why can't we use the Enter button to confirm actions?
